We describe percutaneous closure of an unusual paravalvular leak, with a communication from the noncoronary cusp of the aortic valve to the left atrium adjacent to a St. Jude mitral valve prosthesis, in the absence of an infection. The patient presented with worsening dyspnea and edema. The anatomic location of the valve annulus adjacent to the noncoronary cusp underlies the etiology of this communication. Outcomes from surgical repair are associated with high mortality. We performed percutaneous closure of the defect, using general anesthesia and transesophageal echo guidance. An Amplatzer duct occluder was placed in the fistula, with immediate and complete closure of the shunt. While no devices specific for closure of paravalvular leaks have been designed, growing experience with a variety of devices and the use of echo guidance have allowed successful therapy in many complex cases.
